' SEAT SUPPORT.

Application filed April 17, 1925. Serial No. 23,758.

such as is provided for bicycles, motor-p cycles and other vehicles. l

It is a more particular object ot" the invention to provide auxiliarycushioning means interposed between the vertical spring post for thesaddle or seat and the under side of said seat and connected with thelatter whereby abnormal shocks or jars will be effectively absorbed.

ln one practical embodiment of my present improvements, I provide alaminated leat spring structure extending' longitudinally beneath theseat and connected at its torward end with the vehicle frame, said leat'spring at its rear end having sliding engagement with anti-frictionbearing means lixed to the rear end of the seat and intermediate o'f itsends having sliding conne@ tion with the upper end of the spring postfor the seat.

lt is another object of my invention to provide means whereby certainoit t-he'leaves or laminations of the cushioning spring may belongitudinally adjusted relative to the others and with respect to thepoint of connection of said spring with the upper end ot the seat post.

With the above and other objects in view, the invention consists in theimproved seat support and in the forni construction and relativearrangement ot' the several. parts thereof as will be hereinafter vmoreYfully de` scribed, illust-rated in the accompanying drawing, andsubsequently incorporated in the subjoined claims. Y

Referring in detail to the drawing, 5 designates a portion of thevehicle frame in which the vertically movable spring post 6 Jfor' thesupport of the seat or saddle is mounted in the usual manner. The saddleseat may be oit' any approved construction and is provided at its rearend with the usual cantle plate 9. The customary wire spring 10 is alsoarranged beneath the seat Jfor the purpose of longitudinally tensioningtlierlatter and as herein shown is provided with a transverseintermediate portion 11 seated under a curved lip 12. on the forwardedge of the cantle plate 9. At opposite ends of said intermediateportion 11, this wire spring is lixed to the cantley plate by suitablebolts 13. Y The spaced side portions of theA spring 10 areforwardlyextended from the cantle plate beneath the seat'l, in convergentrelation to each other and are suitably connected with a plate 14 fixedto the under sideol the front end or pommel of the seat, as for instanceby means of a suitable bolt indicated at l5.

l To the opposite sides ofthe longitudinal bar of the frame 5 theupwardly projecting plates 16 are rigidly lixed by the transverse bolt17 and between the upper ends of these plates the forward end ot' alongitudinally disposed channel shaped bar 18 is pivotally mounted uponthe transverse bolt 19. The rear end of this bar is connected with theforward end of the saddle seat by` the bolt as clearly shown in Fig. 1of the drawings.

Upon the upper end of the springpost G a horizontally disposed plate 20having side flanges 21 is rigidly fixed. These flanges adjacent theiropposite ends are notched or recessed to receive the ends of the spacedbearing rollers 22., The rollers are retained in said seats by the sidewalls of a vertical loi;

U-shaped housing 23, said side walls being fixed to the flanges 21 bythe screws 24.l The top wall of this housing adjacent its forward end isformed with a pocket or seat 2 5 for an upper bearing roller 26positioned in the vertical plane of the forward lower bearing roller 22.

Supplementing the sustaining actionV of this auxiliary cushioning springhas its for-I ward end 28 downwardly extended and en.

gaged against the under side of the sleeve on the forward end 'of thespring leaf 2T as shown in Fig. 1 of the drawings. Beneath the leaf 2Sthe additional spring leaves 30 and 31 respectively are arranged, saidvlower leaf 31 being connected at its rear end with a bolt 32 whichconnects the ends of a U-shaped clip member 33 embracing the severalleaves or laminations ofthe spring structure at a point rearwardly ofthe bearing housing- 23. It will be noted that the several leaves orlaminations of the spring successively decrease in length from the uppertoy the lower lamination, and therefore offer successively increasingresistance to vertically applied pressure. For the purpose of Yregulating thisy resistance, I provide the two lower leaves 3,0l and- 31adjacent their forward endswith suitable notches orV recesses 34 for thepurpose of receiving the` bolts 35` connecting theends of two transverseplates 36 extending above and below the series of spring leaves.V Thetwo upperrspring leaves 27 and 28 are provided with a plurality of suchnotches or recesses 37 intheir opposite edges spaced longitudinally fromeach other. Thus, it will be apparent that by shifting the two lowerleaves 30 and 31of the spring longitudinally witlr respect MVto the twoupper leaves and engaging the bolt-S735 in selected recessesor notches37 of the latter leaves, the rear end portions of the lower leaves 30andV 31 may be adjustably...positioned with relation to the bearingrollers 22 and 26 inountedyon the upper end of the spring post G tothereby increase or decrease the resistance oifered by the rear endportion of the laminatedspringstructure to verti cally applied pressure.

To the under side of the cantle plate 9 a plate 3S is fixed at its rearend, the Aforward end of said plate having a Ytransverse seat 35) formedtherein for a bearing roller 40.

rearend to the eantle plate and openl at its forward end. As clearlyshown in Fig. 1 of the drawings, the rear end of the upper leaf 27 ofthe laminated spring structure extends longitudinally into this housingbetween the bearing roller Ll0 and the bottom .wall of the housing andexerts an upward bearing pressure against the under side of said roller.

ln the operation of the device above described, it will be apparent thatthe vxeig t of the rider on the seat 3 4is normally tained by the springpost t3, there being` little ilexure of the longitudinally cxtcndi gjlainii `Led spring structure from its neri dition. -ll'hen, however, thewheelsA of the vehicle encounter' obstructions or ruis in the roadsurface,resulting in an :abnormal sho/.li or jar to the vehicle frame,such sliorl: will be cushioned by the longitudinally filcuding auxiliaryleaf spring, said ,spring at its forward end turning about the bolt iland flexing at its 'rear end as the bearing roller al) moves downwardlyon the upward-` ly curved end of the spring lamination 27. In thisabnormal vertical movement of the seat relative to the vehicle frame,the intermediate portion of the laminated spring will shiftlongitudinally relative to the upper end of the springpost (3 betweenthe bearing rollers 22 and ll. Thus, it will be apparent that in thismanner such shocks or jars will not be transmitted-to the body of the.rider but will be effectively absorbed by the longitudinally extendinglaminated spring interposed between the seat and the supporting post Gtherefor. Bj adjusting the lower spring leaves in the manner aboveexplained, the,responsiveness of the laminated spring structure may beproperly regulated in accordance with the weight of l the rider.

In Figs. 6 to 9 inclusive, I have illustrated an alternative means foryieldably connecting the rear end of the longitudinally extendingkspring with the seat. ln this construct-ion l provide a transverselypositioned multi-ply leaf spring indicated at i2, the central leaf ofwhich is extended beyend the ends of the upper and lower leaves andpivotally connected by the shackles -ri3 with the depending members #iaiwhich are pivotally rsuspended from the transverse pins or bolts t5 inthe rear ends of plates 4 6 which clamp the wire spring 10 to the underside of the cantle plate 9.

The transversely disposed leaf spring ft2 at its center extends over andupon the rear end of the uppermost leaf of the longitudinally positionedspring which is mount edupon the seat vpost in the manner abovedescribed, and is rigidly fixed thereto by means of the bolt 4:7. Itwill be apparent from this construction that the transverse spring 42connecting therear end of the longitudinall spring with the seatprovides loo lltl
